The main page of the site returns an error to Yandex

If you received a message about such an error, follow the following actions:

Check the presence of noindex tag in the page of the page. If it is present, delete it.
Go to the webmaster to the indexing section → Bypass statistics and make sure what response code the page gives to the requests of the Yandex robot. If the response code differs from 200 OK, use the server response tool to find out the reasons.
When checking the server response, make sure that the contents of the page does not indicate the message “There is no contents of the page”. If it is present, check the following points on the server:
- HTTP heading (for example, "Content-Length: 0" may indicate that the page cannot be indexed by a robot).
- The size of the contents of the page (it should be more than zero and correspond to the HTTP-setting).

After corrections, wait for a second visit to the Yandex robot. You can also send a re -exposure page so that the robot visits it for two weeks.

If after the check the page responds with the code of 200 OK and there are no problems with the availability of the contents, the warning will disappear in a few days.

Failed to connect to the server due to DNS error in Yandex

Every day, the Yandex indexing robot addresses DNS servers to obtain the IP address of the site. If the DNS records are incorrectly configured, the robot cannot connect to the site, which prevents its indexation.

To eliminate the problem, check the correctness of the server response to the robot requests. If the error continues to occur, contact the hosting provider to adjust your domain DNS-records. After accessing access, the information in the webmaster will be updated for several days.

If the problem is short -term, and there are no errors of errors when re -checking the response of the server, wait for the data update in the webmaster.

If the domain was not extended on time, the site will become unavailable for indexation. In this case, it is necessary to extend the registration of the domain, and the problem will disappear within a few days.

The site is closed for indexing in the Robots.txt file to Yandex

The Yandex indexing robot several times a day requests the Robots.txt file and updates information about it in its database. If the file has a prohibition directive, the webmaster will display the corresponding warning.

Check the contents of the Robots.txt file and delete the ban if it is present. If you cannot do it yourself, contact the hosting provider. After making changes, the information in the webmaster will be updated in a few days.

Also, a warning may appear in the case:

If the domain has not been extended on time - the Robots.txt file may contain prohibition directives.
If your site is available by HTTP and HTTPS, and only HTTP addresses are added to the webmaster, this can lead to an error.

So that your site is indexed by https:

Add the address with HTTPS protocol to the webmaster.
Configure redirecting from HTTP version to HTTPS version.
Send a request for moving to the webmaster.

When the robot visits the site and receives information about changes, the warning will disappear.
